【MAC 上学习 C++】Day 49-1. 实验8-1-2 计

实验8-1-2 计算两数的和与差 (10 分)

1. 题目摘自

https://pintia.cn/problem-sets/13/problems/546

2. 题目内容

本题要求实现一个计算输入的两数的和与差的简单函数。

函数接口定义：

void sum_diff( float op1, float op2, float psum, float pdiff );
其中op1和op2是输入的两个实数，psum和pdiff是计算得出的和与差。

输入样例：

4 6

输出样例：

The sum is 10.00
The diff is -2.00

3. 源码参考

#include <iostream>
#include <iomanip>

using namespace std;

void sum_diff( float op1, float op2, float *psum, float *pdiff );

int main()
{
    float a, b, sum, diff;

    cin >> a >> b;
    sum_diff(a, b, &sum, &diff);

    cout << fixed << setprecision(2);
    cout << "The sum is " << sum << endl;
    cout << "The diff is " << diff << endl;
    
    return 0; 
}

void sum_diff( float op1, float op2, float *psum, float *pdiff )
{
  *psum = op1 + op2;
  *pdiff = op1 - op2;
  
  return;
}
